Bluetooth Solution

CSR plc launches its fifth generation of BlueCore, a Bluetooth hardware and software solution. CSR also today launched its BlueMedia enhancements using new DSPs embedded inside the ICs to bring both improved audio performance and added radio functionality. BlueMedia enhanced DSP brings significant improvements to CSR's existing multimedia BlueCore silicon. BlueCore5-Multimedia includes a doubling of the processing power of the DSP co-processor to 64MIPS. The on-chip memory in BlueCore5-Multimedia has also been upgraded to 156 kb SRAM and improvements to the internal stereo analog CODECs now provide up to 90 dB signal to noise ratio. The BlueCore5-Multimedia IC is aimed at the increasingly sophisticated Bluetooth accessory market including mono and stereo headsets, automotive systems and music players. This chip combines a fifth generation Bluetooth core, and uses the BlueMedia enhancement to embed CSR's latest generation ClearVoiceCapture (CVC) technology for improved on-chip echo cancellation and noise suppression.
